Seeing Yang Dong's determined expression, Lu Lao's cheeks were also a little hesitant.

Although he had never seen this kid strike iron, every time he put forward an idea, he would have a refreshing and even shocking feeling.

Not to mention anything else, the cannon battle that the cold palace manufacturing plant relies on to survive is the formula provided by this young man.

Thinking of this, Lu Lao looked at Yang Dong seriously and asked:

"Yang Dong, are you really so sure?"

"Of course!"

Yang Dong nodded seriously, and then seemed to remember something, and added another sentence.

"I deeply regret the situation of the previous senior. But did Lu Lao ever think that we can conduct experiments according to the control variable method. ”

"Control Variable Method?"

Lu Lao frowned, he didn't understand what Yang Dong meant. But it sounds like a pretty big deal.

"The control variable method, simply put, is that we change only one or two variables in experiments that are as consistent as possible."

"For example, when we cook rice, we make sure that the amount of rice is constant, and add different amounts of water to observe the softness and hardness of the final rice, so as to achieve an optimal rice taste."

After saying this, Yang Dong paused and continued:

"Of course, when cooking rice, the size of the pot, the material, and the heat are all variables. The smaller we keep these variables in, the stronger the correlation between the amount of water added and the softness of the rice, the more accurate the results will be. ”

Hearing him explain this, Lu Lao's originally puzzled eyes gradually brightened.

This time, he finally understood what Yang Dong meant. To put it simply, it is to determine the best solution through experimentation.

In fact, this is not a new method at all, and many craftsmen will continue to optimize some tools and accessories according to the current situation when they are working.

It's just that these things all vary from person to person, and there is no professional system formed from this.

But after listening to Yang Dong's description, Lu Lao suddenly felt that if a standard was formulated and all blacksmiths were to abide by it, then the experiment would definitely have twice the result with half the effort!

Thinking of this, Lu Lao stood up abruptly and pressed Yang Dong's small body.

"Boy, tell the teacher honestly, how many treasures are still hidden in your brain?"

Yang Dong wanted to resist, but the true qi on Lu Lao's body instantly made the power of qi and blood in his body lie down. Although the pink true qi is still resisting stubbornly, and even faintly resists, but its number is too small.

Although the quality is obviously superior, the difference in quantity is like a small river and a large river......

Lu Lao felt that the kid under him actually dared to resist, and he could resist, and between his eyebrows, he couldn't help but show a look of surprise.

This kid is really not as simple as it seems on the surface.

At the same time, after resisting to no avail, Yang Dong really raised his hands and chose to surrender.

Anyway, it's my own master, so it's not a shame to surrender, right?

"Master, don't be like this, let go, hey!"

"Okay, I'll tell you, I'll tell you everything!"

Yang Dong spread his hands helplessly, and Lu Lao put him down.

Yang Dong rubbed his sore shoulders, and couldn't help but feel a wave of guilt in his heart.

Lu Lao is worthy of being born in iron, and the power of this palm is simply amazing, just that terrifying physical power makes him, a great martial artist, a little unbearable.

However, people say that when you are promoted to the innate realm, you will go through a process of washing the essence and cutting the marrow.

Then the body of the martial artist will be enhanced like never before, which may be why Lu Lao's palm is so powerful!

Yang Dong thought so and continued to speak:

"Old Lu, have you cooked on weekdays?"

Lu Lao was caught off guard by Yang Dong's sudden question.

He looked at this kid in surprise, and couldn't help but ask:

"Boy, gentleman is far away, haven't you heard of it?"

Yang Dong glanced at his mouth, sure enough, feudal thinking kills people!

You don't see that the master relied on an authentic barbecue at the beginning, and he subdued the brutal and willful little princess of Houjin, and since then, she has been obedient to the master!

Thinking of this, he suddenly realized that since he left Youzhou and Wan Yanyue was picked up by Houjin, the two of them had not been in touch for a long time.

Counting the days, it has been half a year to say the least.

I don't know if she mixed well in Houjin Wangting, and whether she was bullied by her two sisters......

Thinking about it, Yang Dong laughed again.

He felt that his worries were too unnecessary. With Wan Yanyue's means and thoughts, she may be more worried about her two sisters.

Ahem, think far away......

Yang Dong retracted his thoughts and said with a straight face:

"Lu Lao, I didn't say you, the pattern is small! Do you know that everything in this world has its own unique laws? That's why I opened a subject called Gewu in Lanxiang Academy. ”

"You can only know by studying things, you don't want to underestimate this small kitchen, there is a lot of knowledge in it!"

Lu Lao chuckled, but his face showed a look of indifference.

"If that's what you say, then you should tell me what kind of knowledge can be learned in this kitchen!"

Yang Dong smiled faintly and put on a confident look.

"Lu Lao, you should know that after heating, water and oil can boil."

Recently, Lu Lao has been boiling water a lot. Therefore, it is understandable what Yang Dong said, so he nodded and said:

"The old man naturally knows, but so what?"

"Old Lu, you only know one thing, but you don't know the other. In fact, the boiling point of water and oil is not the same...... Well, the so-called boiling point refers to the temperature at which it boils. Uh – Temperature means, it's a unit of measurement of hot and cold. ”

"These are not important, the important thing is that because of the different boiling points, when the boiling hot oil is suddenly mixed with the boiling hot water, there will be a very violent explosion!"

As soon as these words came out, Lu Lao's face changed slightly.

He seemed to have figured out something, and the expression on his face suddenly became extremely serious.

"Are you telling the old man that the senior, it was because of the different boiling points of the two metals after they melted that there was an explosion when they were mixed?"

Yang Dong nodded,

"Although I don't know what the situation was at the time, what it was. But I think it is possible that this situation was the cause of his death. ”

"If Lu Lao doesn't believe it, you'll know it by trying."
